Are you allowed to enter a structure with a D-Fault?

• A. No
• B. Yes
• C. Only with supervisor approval
• D. Only if wearing PPE

Answer: (A)

Entering a structure with a D-Fault is not allowed because a D-Fault signals a hazardous condition that could still energize equipment, cause an arc flash, or create other dangerous situations. PPE by itself does not remove the underlying risk, and supervisor approval cannot override the safety rule that the area must be safe before entry. The proper response is to treat the area as unsafe, secure it, and follow the established process to address the fault—typically isolating energy sources, verifying zero energy, and obtaining the appropriate authorization or permit to work—before anyone enters.
